My invention has for its object to furnish. an improged governor for regulating the velocityvoi` Amachines driven by steam, wind, or water power; and it consists, iirst, in the combination of the pulley, pinion-wheel, bevel gear-wheels, and frame or box, with each other, with the driving and Iverge-wheel shafts, with the rack, and with the frame of the machine, for the purpose of obtaining the difference between the motion of the machine to be governed, and the required motion second, in the combination of thejointed verge with the verge-wheel with the pendulum and vibrating-wheel, either or both, and with the frame of the machine; third, in the combination of the Spring, pitman, lever, a'nd vibrating-frame, with each other, with the vibratingwheel, and with the frame of the machine; fourth, in the combination of a pawl, ratchet-wheel, windlass and cord, with each other,with the frame of the machine, and with therpend'ulum weight; fifth, in the combination of the spring-catch and pulley with the drivingshaft, with the rack, and with the frame of the machine ;Y sixth, inthe combination of a `jointed lever and stirrup with the rack and with a fulcr1impost; the whole being constructed and arranged as hereinafter more fully describ ed.

A is the driving-pulley, around which passes a band connecting it to the machine to be governed. The pulley A is attached to the end ofthe driving-shaft B, which revolves in bearings C, attached to the post d1 of the frame l) of the machine, and the other end of which revolves in a 'socket formed'in the hub of the frame or box E. F is a bevel gear-wheel attached to the end of the driving-shaft B, as shown in g. 6, the teeth of which mesh into the teeth of' the bevel gear-wheel Gpivoted to the frame or box E, and impartfmotion to said wheel. The teeth of the bevel gear-wheel G mesh into the teeth of the bevel gear-wheel H attached to therend of the verge-shaft I, as shown in iig. 1. The shaft vI revolves in bearings il, attached tothe posts cl2 and d3 of the'frame D, and its end enters and revolves in a socket formed in the hub of the wheel or frame E. The frame E is thus supported upon and pivoted to the ends of the shafts B and I. K is a'piniomwhecl attached to the, part el of the frame E, which revolves loosely upon the shaft B, and the teeth of which mesh into the teethof `the rack L. The rack slides up and down through the top piece d4 of the frame D, and is kept in yplace by the guide M attached to the post d'1 of the frame l), as shown in iig. 1.' To the top of the rack L is attached a stirrup, N, through which passes the end of the lever O. The lever O is pivoted to the fulcrum-post l?, and is jointed or has a short lever, ol, pivoted to its end. One end of the part ol is connectedV to the valve or gate thatfregulates the power, and from the other end is suspended a weight, R, to hold the said part in its place. S is a weight suspended from the ertd of the lever O to hold it toits place. The stirrup N is made adjustable by being secured tc the rack Liby a screw, nl, as shown in figs 1, 2, and 5. This enables the machine and fulcrum-post, P, to be set in any desired position to accommodate the positions of the power and machine whose motion is to be governed. T is a weight attached to the rack L, as show 'n in iig. 2, which draws said rackv down and operates the valve whenever the motion ci' the machine to be governed stops or becomes too slow. V is a spring-catch, the spring, ul, of which rests upon the pulley V attached to the shaft B, and 'its upper end is attached to the part, u2, which works in supports attached tothe frame D, as shown in gs. 1 and 3. The lcatch a3 is attached to the part faz, and hangs down in front of the rack L, as shown in gs. land 5. Whenever the pulley A runs back, the pulley Voperates the spring-catch U, bringing the catch ua in contact with the teeth of the rack L, holdingv the said rack securely in such position, as shown in fig. 5.. W is the 4verge-wheel, which is attached to the end of the .shaft I, as shown in fig. 1. The verge-wheel W has two points or arms,A as shown in tig. 4, each of which operates each part of they jointed verge, X, at Veach revolut'ionvofl the said wheel, W, thus communicating tour vibrations tothe pendulum or vibrating-wheel at each revolution of the said verge-wheel W. X is the jointed verge, both parts, x1 and a, of which are pivoted to the side of the post d3 of the frame D, as shown iniig.` 4, in such positions that they may both be acted upon by the arms or points ,of 4'the verge-wheel W. The' parts x1 and' as are connected to each other by thepitman, a3, th'e lower end of which is pivoted to the angle of the part w1, and its other end' is pivoted to the end of the arm x1, rigidly attached to the part x1. A1 is the pendulum-shaft, which works in bearings attached to posts Z2 d3 ofthe frame D. To the end of the shaft A1 is attached the pen dulum-rod B1, which passes through a slot inthe pendulum-weight U1, as shown in dotted lines in lig. l. a1 an arm rigidly attached to the shaft A1, and to the lower end of which is pivoted the upper end of the pitman D1 which connects the pendulum to the jointed verge X.- Through the lower end of the pitman D1 is formed a hole, and from the side qflthe upper-part, :1:1 of thevege X, projects a pin, upon the end of which rests one end of a springe, and the connection is made by Islipping the end of the pitman under the spring a so that the saidl pin may passthrougih the hole in said pitman. E1 is a windlass working in Isupports, F1 attached to the frame D, as shown in iig. 1. G1 is la pawl pivoted to the frame" D, and taking holdV of the teeth of the ratchetewheel H1 attached to the windlass E1 to hold said windlass in any position in which it maybe placed. I1 is a cord, one? end of which is vattached to a hook uponthe Ashaft of the windlasstE1', and its other end passed down througlla. hole in the guiderest J1 and is attached to the pendulum-weight C1, so that by operating Ithe windlass E1 the' said weightmay be raised or lowered, and the rapidity of the motion thus' increased or diminished as desired. When desired, the cord 11 may be removed from the shaft of the windlass B11-,passed over the pulley K1 thence carried along the top piece d* of the frame D, over the pulley L1 `attached to saidtop piece. and secured to a hook attached to thev rack-weight T, as shown4 in red in ,'figs. 1' and 5. This arrangement is designed to govern a saw to run fast while sawing and slow while not sawing, regulatingl the motion according to the' power required. M1 is a-vibrating-wheel, the axles of-which work in bearings attached' to the posts d1 and da .of the frame D. To one end of the axle of the wheel lM1 is attached a crank, N1 to the end of which is pivotjed one end of the arm P1 having asmall spring, p1 attached to it, the end of which rests upon the end of a pin projecting lfrom the side of said arm. Through the lower end .of the part z2, of the jointed verge X, is formed a hole through "which, is passed the pin on the arm P1 thus connecting the jointed verge X to thevibrating-wheel M1 To the other end of the axle of the vibratingwheel M1 is attached-a crank-R1 tothe end of whicli'is pivoted one end of the pitman S1 the other end of which is -pivoted to one end'of the vibrating-frame T1 the shaft t1 of which works in v hearings secured to the posts' d2 :indd3 of the frame D, as shown in fig. 1. U1 is a'lever having a pin, with the end of a small'xspring restingupon its end, in the manner before described. This lever isconnected to the yvibrating-frame T1 by passing the said pin through one or the other of the holes through the bar tY of the said frame, according as the motion ofthe vibrating-wheel M1is desired to befaster or slower. The other end of the lever` U1 is pivoted to the lower end of the arm V1, the upper end ofrwhich works looselyvupon the axle of the vibrating-wheel M1 W1 is the spring that regulates the movement of the vibrating-wheel M1 Oneend of the spring W1 is securelyattached lto the axle ofthe wheelAM1 and the other end to the lower part of the arm Y1 as shown in fig. 7. The vibration of the wheel M1 is also limited by the stop-pins X1 projecting from the side of the rim of said wheel, as'ishown in figs. 1, 2, and T, which'said pins come in contact with the pin S1 projecting from the sill d5 of the frame D, and prevent the said wheel from revolving too far.

I It will be observed that either the lpendulum o'r the vibrating-wheel, or both, may be used to mark the required velocity. And it should ,be remarked that whenthe pendulum alone is used the upper part, x1 'of the jointed verge, X, 4may be attached directly to the pendulum-shaft A1 It should also be observed thatthe rack L, that regulates the application of the power, lis operated by the diiference between the required motion andthe actual motionof the machine to be governed, being raised if said machine runs too fast, vand lowered if it runs too slow. I n
